Google Wave now gives bloggers, corporate intranets, and other potential Wave users a way to let the public watch what's going on in a Wave and, for the truly daring, invite any Wave user to edit.

Gina Trapani is demonstrating a live, public-edited Wave right now at her Smarterware post, but there are more calm, restricted uses of an embedded wave, too. Blogs can host discussions between a group of participants for all to see, with or without Wave access, and small teams working on a project can create a go-to spot that always has a relevant Wave embedded, so it doesn't get lost in any user's Wave inbox.
